iachar(3I)

NAME
     IACHAR - Returns the position of a character in the ASCII collating
     sequence

SYNOPSIS
     IACHAR ([C=]c)

IMPLEMENTATION
     UNICOS, UNICOS/mk, IRIX systems

     CF90, MIPSpro 7 Fortran 90

STANDARDS
     Fortran

DESCRIPTION
     The IACHAR intrinsic function returns the position of a character in
     the ASCII collating sequence.  It accepts the following argument:

     c         Must be of type character and of length 1.

     IACHAR is an elemental function.  The name of this intrinsic cannot be
     passed as an argument.

RETURN VALUES
     The result type is a default integer value.  If c is in the collating
     sequence defined by the codes specified in ISO 646:1983 (International
     Reference Version), the result is the position of c in that sequence
     and satisfies the inequality (0 <= IACHAR (c) <= 127).  The results
     are consistent with the LGE, LGT, LLE, and LLT lexical comparison
     functions.  For example, if LLE(C,D) is true, IACHAR(C).LE.IACHAR(D)
     is true when C and D are any two ASCII characters.

EXAMPLES
     IACHAR('X') has the value 88.
